well am using regular is that bad . should i start using premium, but doesnt the car start bogging if you switch it back to regular unleaded. And is their really a big difference in power if i use premium?

 

use premium. if you're too cheap or can't afford the extra 3 dollar a tank, you shouldn't have gotten a car that calls for it.

if you are using regular, hope you never really drive the car hard. but yea, should be using premium. you CAN use lower grade gas, but you really shouldn't.

 

Regular is bad for your car. Only use premium.

 

If you can always use premium. You may not notice any difference now but eventually it'll catch up to you.

Laredo Texas, fun place to visit

 

i have had problems when using reg, stick to premi

 

you're leaving yourself open to getting knock...the car has an octane sensor so it can retard the timing but there's a reason the car is supposed to get 91 or higher...

 

Use premium you won't regret it. Use regular and youll be kickin yourself for bein to cheap. 20 or 30 cents more. Your talkin a little over 3 dollars more to be safe and keep your car in good condition.

 

did you read your owners manual?

 

It has nothing to do with "POWER"

It has to do with what the engine is designed to use..

 

yes regular is bad.
yes you should have been using premium every single fill from the beginning.

Yes it will probably bog if you go back to regular.
yes there is a power difference to using premium.

You car is also going to knock itself to death if you keep using that cheap fuel.

premium isnt optional for the cobalt SS.
its a requirement.

 

its a cobalt....

 

what you mean by that

 

im pretty sure guys in GM made the car so it can run on regular gasoline i dont think itll hurt that 2.0 S/C if you use regular gas im pretty sure there would be an octane warning on the blower, engine or gauge cluster

 

thanks guys for the advice

 

they didnt make the car to run on regular gasoline. they made it to run on premium.

Read the manual.

 

in the owners manual it states that the ss/sc 2.0l needs to use 91 or higher octane and thing lower will casue knock

damn you beat me to it

 

haha cobalt guys...you know they put that on there to make you feel fast but seriosly it doesnt HAVE to take 91 octane it can run off 89..

 

k. i was trying to be nice.

but if your just gonna be ignorant, then believe what you want.
your car will run great on 87.
seriously.
please use it.

 

ok sure use it also you know what dont even use mobile 1 just use another brand oil like valvoline 10w 30

 

no i cant but you can you see my motor actually has an octane warning and produces alot of power to which i need to use 91 as well its tuned for it

no i use the higher rated oils too

 

You should fill up your tank with premium and then drive it home and disconnect the battery for at least an hour. That will reset all the tuning (de-tuning) adjustments your car has made to itself from using 87 octane.

I guarantee the next time you drive your car you will be able to tell the difference.

 

why not tune with 93 and which oils you use and what cobalt do you have if you have one

 

ahhhhhhh
i should have seen it sooner

 

that sounds like a waste of time moron

 

wow. it must be retarded troll night.
